<p>A cigarette includes a charge or roll of smokable material (e.g., tobacco cut filler) circumscribed by at least one layer of paper wrapping material to form a tobacco rod. A certain cigarette includes an outer wrapping material which circumscribes and overwraps an inner wrapping material. The outer paper wrapping material of the tobacco rod includes an additive package. The additive package includes at least one water soluble salt which is applied in a water soluble form. For example, a paper wrapper including wood pulp fiber and calcium carbonate filler material is treated with an aqueous solution of calcium acetate, potassium chloride and potassium acetate. The inner paper wrapping material includes flax fiber, magnesium hydroxide filler and calcium carbonate filler. The cigarette is capable of sustaining smolder under FTC smoking conditions while yielding very low levels of visible sidestream smoke.</p> |
